1/R=1\R1+1\R2+1\R3...1\Rn
when resistors are connected in parallel the voltage is same across each resistor V=V1=V2=V3...Vn -1equation
and the total current is equal to the sum of the individual currents I=I1+I2+I3...+In-2equation
according to the ohms law i=v/R
substitute in the 2 equation
v/R=v/R1+V/R2+V/R3..+V/Rn
v(1/R)=v(1/R1+1/R2+1/R3...+1/Rn)
1/R=1\R1+1\R2+1\R3...1\Rn
